Just switched my first pair off my Versys at 26500 km. Still not down to the wear bars, but squared in the back and scalloped up front to the point that I just wanted them switched. These were amazing tires in the rain up to almost 25000 km, smooth to ride on, and much less squishy than I would of expected given the number of sypes in them. The only downside is that they are spendy, but given that they lasted 1.5-2x the life of cheaper tires, and how well they performed over that time, I replaced them with another set of the same. Might not last as long on a heavier bike with a heavier rider, but I was pretty happy with how mine did.
